import java.awt.*;

        panel.setLayout(new BorderLayout());
        panel.setSize(400, 1000);

        JLabel testing = new JLabel("testing1");

        JLabel testing2 = new JLabel("testing2");
        panel.add(testing, BorderLayout.CENTER);

        JLabel testing3 = new JLabel("testing3");
        panel.add(testing2, BorderLayout.PAGE_END);

        scroller = new JScrollPane(panel);
        scroller.setSize(100,100);
        add(scroller, BorderLayout.LINE_START);

    }

    public static void main(String args[]){
        ExamKnee2 examKnee = new ExamKnee2("Right", "123-45-6789", "2
weeks");
    }
}

All I am trying to do is get the scroll pane to scroll vertically.
Will not do it. This is really pissing me off. According to the java
tutorial (found here
http://java.sun.com/docs/books/tutorial/uiswing/layout/border.html)
the "testing" labels should be displayed horizontally. Secondly, I
should be able to scroll around to view the 3rd testing label but I
cant. I know theres more problems but im a lil piissed off right now
becuase this isnt working. please help...
